No modifications working on Tahoe

[petr-nehez]

Since the time I upgrade my Mac to Tahoe 26 KE does not work at all.

I have the version 15.9, uninstalled and installed again, granted FullDiskAccess to Karabiner-Core-Service but still modifications do not apply. I can see correct keys reported in Karabiner-EventViewer.

I can see error in log:

Same issue here; even enabled third-party kernel extensions from the Security Policy menu at boot. Turns out there's an announcement at https://karabiner-elements.pqrs.org/ saying that the developers are working on a patch.

Something to do with macOS key mappings being changed in 26.4 beta 1.

[petr-nehez]

I dont't have 26.4 beta, I'm on 26.2.

[jspiro]

It also broke combining keys from multiple keyboards. I have a habit of pressing a modifier on an external keyboard with a left hand and using the trackpad on the macbook, sometimes hitting cmd on my left hand and another key like delete or down on the internal keyboard. Not even SHIFT + key on internal keyboard works. It's more accessible.

Reported it in feedback. This is bs, apple.

Same in 26.3. No complex modifications works(In my case it's capslock modification on builtin keyboard, I don't have an external one to test).

My fix was to enable full disk access to karabiner_grabber(Probably because my config file is a symlink to another folder)

[jspiro]

Seems fixed in 26.4 Beta 3, thank goodness. What a mess 26.4 has been.
